Datafolha survey released on Friday (22) points to an advantage for Luiz Inácio Lula da Silva over Flávio Bolsonaro in the presidential race.
The survey polled 2,004 voters between May 20 and 21 and has a margin of error of two percentage points.
In the first round, Lula appears with 40% of voting intentions, against 31% for Flávio Bolsonaro. In the second round, the president has 47% and the PL senator, 43%.
Flávio's allies treated the four-point drop as a scratch and said the candidacy remains competitive. PT members expected a greater impact from the Dark Horse case on voting intentions.
